Over the past 12 months, several animals have died, including a beluga and a walrus, according to Phil Demers, a former senior marine mammal trainer at Marineland — yet the park hasn’t uttered a word about these deaths.

Demers, who’s spent the last six years in a legal battle with Marineland over its mistreatment of animals, told The Dodo that he learned about these deaths from a current Marineland employee.

“We recently got an up-to-date list of all the belugas, their sex and their ages, and which pools they’re in at Marineland,” Demers said. “My girlfriend and I scoured over this, and we noticed the names of missing belugas.”

Two belugas missing from the list were Burnaby and Horus. Demers has recently received confirmation that Burnaby recently died, although the park never announced it. While it isn’t clear if Horus is still alive, Demers believes his absence from the list is very telling.

Demers also received word that a walrus named Buttercup died over the winter, shortly after another walrus named Sonja died. While the park announced Sonja’s death, it kept Buttercup’s quiet.

“This is the one that’s really concerning,” Demers said. “Sonja just died last year, and between Buttercup and Sonja, they were the two healthiest walruses. They were the picture-perfect, healthiest animals that we had, so whatever is going on at Marineland right now, it’s bad news. We’re down to three walruses out of nine.”

Demers is also extremely worried about Smooshi, a walrus with a history of chronic regurgitation issues, a sign of captive stress, which caused her to lose a lot of weight.

When he still worked at the park, Demers had formed an unusually close bond with Smooshi during a stressful situation — an employee was drawing blood from another walrus, and Smooshi tried to intervene.

“Smooshi came around and she was trying to protect the other walrus,” Demers told The Dodo in 2017. “I tried to console Smooshi. I think in that heightened state of emotion … her brain circuitry opened, and that’s when the imprinting actually happened. From that moment, she followed me everywhere. I became her mother, scientifically speaking. And she would follow me and protect me, as she would her mother.”

When Demers resigned from Marineland in 2012, he tried to make arrangements with the park to continue seeing Smooshi. However, the park stopped allowing Demers onto its premises, and Demers believes Smooshi’s health has declined since their separation. While Smooshi has made an occasional appearance at the park, she usually remains hidden from public view.

Demers isn’t exactly sure what killed Sonja and Buttercup, although Marineland claimed that Sonja died from a rare abdominal aneurysm. However, he’s certain that Smooshi is at great risk right now. He ultimately hopes that Marineland will turn Smooshi over to him, so he can place her in a legitimate marine sanctuary.

“I’ve been fighting for her for six years now with the aspiration of being reunited,” Demers said. “We’ve never been closer, but we’ve never been further away. Walruses are dying, and there’s no rhyme or reason — the healthiest walruses have fallen off. It’s just a really tense situation right now.”

Marineland did not immediately respond to The Dodo's request for comment.
